Problems solved by technology

In the Q-learning-based adaptive routing protocol (QELAR), the reward function is defined according to the remaining energy of the sensor nodes, and the network lifetime is extended by selecting the next-hop node with more remaining energy, but each node needs to exchange metadata packets Learn the surrounding network environment to determine the forwarding node of the next hop, which will cause each node to consume more energy; in addition, QELAR does not strictly control the network end-to-end delay when selecting the next hop node with more energy; moreover , the routing algorithm that relies on immediate rewards will make the path selection fall into a local optimum, not a global optimum
In the same delay-sensitive QDAR routing protocol based on Q-learning, by defining a behavior-utility function that comprehensively considers the residual energy and propagation delay, the route is adaptively selected to prolong the network life, but the source node must send data packets to the network in advance. Broadcast preparation information, the surface receiver receives the information and makes path planning, then passes the routing information to the source node along the planned path, the source node then sends the data packet, and the selected forwarding node transmits the data packet, this process Will consume a lot of energy in a network of underwater acoustic sensors with long delays
[0006] For the research of UWSNs on detecting underwater information with AUV as the source node and transmitting the data to the sink node, there is no routing protocol that effectively solves the problem of low data delivery rate, high energy consumption, and short network life in UWSNs, so researchers need to pay attention And committed to research in this area, in order to establish a more efficient and low-consumption underwater wireless sensor network

Abstract

The invention discloses a UWSNs multi-hop routing method based on AUV networking. The UWSNs multi-hop routing method comprises the following steps: establishing a first virtual pipeline, a second virtual pipeline and a third virtual pipeline; based on the first virtual pipeline, using an offline reinforcement learning method to obtain a first optimal relay node; based on the second virtual pipeline, obtaining a second optimal relay node by using an offline reinforcement learning method and an online reinforcement learning method; based on a third virtual pipeline, a storage-carrying-forwarding mechanism is adopted, and data collected by the AUV for multiple times are forwarded to a third optimal relay node at the same time; and forwarding the collected data to the first Sink node, the second Sink node and the third Sink node through the first optimal relay node, the second optimal relay node and the third optimal relay node to complete a data forwarding task. The invention provides a routing protocol which effectively solves the problems of low data delivery rate, high energy consumption and short network life in UWSNs.

Description
